Upload a CSV file via PHP and Insert Into MySQL DB - php

Question

No error messages appear on the page. Upload File button works. Upload button doesn't trigger db insert but the page refreshes as if it did.
I am not sure if the array of data from Excel is being coded correctly on the INSERT Into command. Any help is appreciated but PLEASE keep it simple. I am not a seasoned developer. Very green and primarily use procedural coding. If you use an experienced term, don't assume I know what it means.
PHP - if Post Submit button code. The errorMsg doesn't display if no file is attached and submit button is clicked
var_dump($_POST);
if (isset($_POST['submit'])) {
//print_r($_FILES);
$ok = 'true';
$file = $_FILES['csv_file']['tmp_name'];
$handle = fopen($file, "r");
echo ++$x;
if ($handle !== FALSE){
$errorMsg = "<br /><div align='center'><font color='red'>Please select a CSV file to import</font></div>";
$ok = 'false';
echo ++$x;
PHP continued - I'm not seeing the uploaded file populate the database
} else {
print_r(fgetcsv($handle));
while(($filesop = fgetcsv($handle, 1000, ",")) !== FALSE){
$email = mysqli_real_escape_string($con_db, $filesop[0]);
$f_name = mysqli_real_escape_string($con_db, $filesop[1]);
$l_name = mysqli_real_escape_string($con_db, $filesop[2]);
$password = md5(mysqli_real_escape_string($con_db, $filesop[3]));
$zipcode = mysqli_real_escape_string($con_db, $filesop[4]);
$co_id = mysqli_real_escape_string($con_db, $filesop[5]);
$employee = mysqli_real_escape_string($con_db, $filesop[6]);
$assessment_ct = mysqli_real_escape_string($con_db, $filesop[7]);
echo ++$x;
$email = filter_var($email, FILTER_SANITIZE_EMAIL);
if ( strlen($email) > 0) {
echo ++$x;
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo ++$x;
$ok = 'false';
$errorMsg .= 'E-mail address is not correct';
}
}
// error handling for password
if (strlen($password) >= 5) {
echo ++$x;
$ok = 'true';
} else {
echo ++$x;
$ok = 'false';
$errorMsg .= 'Your password is too short (please use at least 5 characters)';
}
// If the tests pass we can insert it into the database.
if ($ok == 'true') {
echo ++$x;
$sql = mysqli_query($con_db, "INSERT INTO `myMembers` (email, f_name, l_name, password, zipcode, co_id, employee, assessment_ct) VALUES ('$email', '$f_name', '$l_name', '$password', '$zipcode', '$co_id', '$employee', '$assessment_ct')") or die ("Shit is not working");
} else {// close if $ok == 'true'
$result = print_r($handle);
echo $handle.'<br>';
echo ++$x;
}
} // close WHILE LOOP
fclose($handle);
if ($sql !== FALSE) {
echo ++$x;
$successMsg = 'Your database has imported successfully!';
//print_r($_FILES);
//header('excel_import.php');
} else {
echo ++$x;
$errorMsg = 'Sorry! There is some problem in the import file.';
//print_r($_FILES);
//header('excel_import.php');
}
} // close if (!is_null($file)){
} // close if $post = submit
HTML Code for the form to submit uploaded file
<form enctype="multipart/form-data" method="POST" action="excel_import.php">
<div align="center">
<label>File Upload: </label><input type="file" id="csv_file" accept=".csv" >
<p>Only Excel.CSV File Import</p>
<input type="submit" name="csv_file" class="btn myButton" value="Upload">
</div>
</form>
</div>
<div><?php echo $errorMsg; ?><?php echo $successMsg; ?></div>

Your submit button does not have a name - and thus $_POST['submit'] is not set. Also, fclose($file) should be fclose($handle). And you should be checking with $handle !== FALSE and $sql !== FALSE rather than with is_null().
